Does water always boil at 100 degrees?

    Not precisely. At sea level, its boiling point is 100 degrees (centigrade); at higher elevations, the boiling point is slightly lower. This is due to decreased atmospheric pressure, which means that the water molecules require less energy to vaporize and escape the pot (or whatever). Conversely, the boiling point will be a little higher below sea level.

    One hundrer degrees celsius is the temperature at which fresh water boils at sea level. At higher altitudes water boils at lower temperatures as the pressure decreases. Salt water boils at a different temperature. In fact, that is the difference between celsius and fahrenheit; the first is based on the boiling and freezing point of fresh water, and the latter is based of saltwater.
